Reman Axle Assembly GM 8.6 09-11 Chevy Tahoe GMC Yukon 3.23 Ratio CORE CHARGE OF $600 APPLIES

The Zumbrota RAA435-172B is a remanufactured complete axle assembly designed for GM 10-bolt applications with an 8.6-inch ring gear. This unit features a 3.23 gear ratio (Option GU5) and an open differential configuration, making it an ideal replacement for units without Posi-Traction or limited-slip capabilities.

The assembly is built to original specifications to ensure factory performance and reliability. It provides a comprehensive solution for axle repair, though it excludes secondary components such as hubs, brakes, backing plates, and axle shafts, which must be transferred from the original unit or sourced separately.

This part is highly application-specific and is intended for select 2009–2011 Chevrolet Tahoe and GMC Yukon models. It is recommended that buyers verify compatibility using the vehicle VIN and option codes to ensure the gear ratio and axle setup match the vehicle's original configuration.

This component is a remanufactured heavy-duty driveline part. Professional installation is recommended, given the weight and mechanical complexity of axle replacement. Ensure the differential is filled with the correct weight gear oil during installation to maintain longevity.
